Dual 2-to-4-Line Decoder/Demultiplexer
CD74AC139 CD74ACT139 dual 2-to-4-line decoders/demultiplexers that utilize Harris Advanced CMOS Logic technology. These devices contain independent binary one-of-four decoders, each with single active enable input 2E). Data select inputs (1A0 2A1) cause four normally HIGH outputs LOW. enable input HIGH, four outputs remain HIGH. demultiplexer operation, enable input data input. enable input also functions chip select when these devices cascaded.
